Properties not inherited from the base binding file.

Name	Type	Details
reset-gpios	phandle-array	RESET pin. The RESET pin of ST7789V is active low. If connected directly the MCU pin should be configured as active low.
cmd-data-gpios	phandle-array	D/CX pin. If configured, 4-lines serial interface is used, otherwise 3-lines serial interface is used and a D/CX bit (9-bit) is added to the protocol. The D/CX pin of ST7789V is active low (transmission command byte). If connected directly the MCU pin should be configured as active low.
x-offset	int	The column offset in pixels of the LCD to the controller memory This property is required.
y-offset	int	The row offset in pixels of the LCD to the controller memory This property is required.
vcom	int	VCOM Setting This property is required.
gctrl	int	Gate Control This property is required.
vrhs	int	VRH Setting
vdvs	int	VDV Setting
mdac	int	Memory Data Access Control This property is required.
lcm	int	LCM Setting This property is required.
colmod	int	Interface Pixel Format This property is required.
gamma	int	Gamma Setting This property is required.
porch-param	uint8-array	Porch Setting This property is required.
cmd2en-param	uint8-array	Command 2 Enable Parameter This property is required.
pwctrl1-param	uint8-array	Power Control 1 Parameter This property is required.
pvgam-param	uint8-array	Positive Voltage Gamma Control Parameter This property is required.
nvgam-param	uint8-array	Negative Voltage Gamma Control Parameter This property is required.
ram-param	uint8-array	RAM Control Parameter This property is required.
rgb-param	uint8-array	RGB Interface Control Parameter This property is required.
spi-max-frequency	int	Maximum clock frequency of device's SPI interface in Hz This property is required.
duplex	int	Duplex mode, full or half. By default it's always full duplex thus 0 as this is, by far, the most common mode. Use the macros not the actual enum value, here is the concordance list (see dt-bindings/spi/spi.h) 0 SPI_FULL_DUPLEX 2048 SPI_HALF_DUPLEX Legal values: 0, 2048
frame-format	int	Motorola or TI frame format. By default it's always Motorola's, thus 0 as this is, by far, the most common format. Use the macros not the actual enum value, here is the concordance list (see dt-bindings/spi/spi.h) 0 SPI_FRAME_FORMAT_MOTOROLA 32768 SPI_FRAME_FORMAT_TI Legal values: 0, 32768
supply-gpios	phandle-array	GPIO specifier that controls power to the device. This property should be provided when the device has a dedicated switch that controls power to the device. The supply state is entirely the responsibility of the device driver. Contrast with vin-supply.
vin-supply	phandle	Reference to the regulator that controls power to the device. The referenced devicetree node must have a regulator compatible. This property should be provided when device power is supplied by a shared regulator. The supply state is dependent on the request status of all devices fed by the regulator. Contrast with supply-gpios. If both properties are provided then the regulator must be requested before the supply GPIOS is set to an active state, and the supply GPIOS must be set to an inactive state before releasing the regulator.
height	int	Height of the panel driven by the controller, with the units in pixels. This property is required.
width	int	Width of the panel driven by the controller, with the units in pixels. This property is required.
